摘　　要：为了研究干扰对航空发动机系统的影响及提高控制系统抗干扰能力,采用基于模型的设计方法(MBD),建立一种大涵道比齿轮传动涡扇发动机(GTF)部件级模型,并且针对发动机干扰来源,根据发生机理建立大气湍流干扰和功率提取干扰模型。基于线性自抗扰控制(LADRC)方法设计了发动机转子转速控制器。在全数字仿真平台和硬件在环仿真平台上对发动机模型、干扰模型以及控制算法进行了集成与验证。结果表明:发动机在面对这些类干扰时,LADRC控制器在转速等重要性能指标上的抗扰能力比PID控制器提高20%以上。LADRC控制具有更好的鲁棒性和抗干扰能力,保证了发动机的平稳运行,为LADRC在实际航空工程中的应用打下了良好的基础。In order to study the influence of disturbance on aeroengine system and improve the anti-disturbance ability of control sys⁃tem,a component level model of geared turbofan engine(GTF)with large bypass ratio was established by Model Based Design method(MBD).Based on the mechanism of engine disturbance,the models of atmospheric turbulence disturbance and power extraction distur⁃bance were established.The engine rotor speed controller was designed based on the linear active disturbance rejection control(LADRC)method.The engine model,disturbance model and control algorithm were integrated and verified on the full digital simulation platform and hardware-in-the-loop(HIL)simulation platform.The results show that the anti-disturbance ability of LADRC controller is more than 20%higher than that of PID controller in speed and other important performance indexes when the engine is facing these kinds of disturbances.LADRC control has better robustness and anti-disturbance ability,which ensures the smooth operation of the engine,and lays a good foun⁃dation for the application of LADRC in practical aviation engineering.
